The present invention relates to a disc holder vertical drive device of a compact disc player, and in particular, the disc can be accurately spindle-mounted without the need to install a separate drive motor for lowering the disc by simplifying parts. The main focus is on seating on the spindle motor and preventing the disk from falling before the disk is completely inserted.

In general, in a front loading compact disc player in which a tray carrying a disc by a motor is reciprocated in a plane, the disc is inserted into the tray and then inserted into the spindle motor. Will be put on.

Therefore, in the related art, there is a problem in that the compact disc player has to be miniaturized due to the increase of parts and the trouble of installing a separate drive motor by lowering the disc by the drive motor.

The present invention has been devised to effectively drive the disk holder up and down without the need to install a separate drive motor to solve the conventional problems as described above in detail by the accompanying drawings as follows.

In a conventional front-loading compact disc player in which a pickup bracket (2) is provided on the deck (1) and a tray (4) with a disc mounting portion (3a) on the top of the deck (1), the disc mounting of the tray (4) is carried out. The hinge rods 9 and 9a of the holder shaft 8 in which the disk holders 6 and 6a and the black jaw 7 are projected to the hinge portions 5 and 5a protruding from one side of the bottom part. ) To be laid, but to be caught on the fixed jaw (1a) protruding from the deck (1) and to form a rack (10) on one side of the pickup bracket (2) by engaging the cam gear (11) to the cam gear shaft (12) both ends The rotating cams 14 having the rotating protrusions 13 and 13a at the same time, are laid out on the supports 15 and 15a mounted on the deck 1, and rotated by the front and rear sliding of the tray 4, respectively. In the drawing, the tip of the holder shaft 8 is inserted so that the disc holders 6 and 6a can be driven up and down by the rotary cam 14. Motor 17 is a disc and 18 is a conveyance rail.

The operation of the present invention configured as described above is as follows.

The tray 4 installed above the deck 1 is slidably moved inside by the transfer rail 18 formed at one side of the bottom surface of the tray 4 in a conventional manner.

At this time, the disc holder (6) (6a) is prevented by the fixed jaw (1a) protruding from the deck (1) and the locking jaw (7) on one side of the disc holder (6) (6a) and then the tray (4) ) Is continuously moved and fully inserted into the center position of the spindle motor 17, and at the same time, the locking jaw 7 on one side of the disc holder 6 and 6a exits from the fixing jaw 1a of the deck 1 and rotates. And the holder shaft 8 residing in the hinge portion 5, 5a of the bottom of the tray 4 in conjunction with the rotary protrusion 13 of the rotary cam 14 as the tray 4 is moved. It is inserted between 13a).

At this time, the rack 10 formed on the pickup bracket 2 and the cam gear are engaged, and when the disk 18 is completely inserted, the pickup bracket 2 allows the pickup bracket 2 to read signals from the inside of the disk 18. ) Moves toward the center of the disk 18 by a slide motor (not shown), and the rack 10 also moves along the cam gear 11 to rotate the rotary cam 14.

Accordingly, the rotary cam 14 in a state where the holder shaft 8, which is extended to the disc holders 6 and 6a while the tray 4 is moved, is inserted into the rotary protrusions 13 and 13a of the rotary cam 14. Rotating protrusions 13 and 13a protruding from the rotating shaft 13 are rotated by the holder shaft 8 and the tip of the holder shaft 8 and the hinge roof 9 and 9a as shown in FIG. The disk holder (6) (6a) is rotated to be lowered and the disk (18) mounted on the disk mounting unit (3) is mounted on the spindle motor (17) to be in an operation completed state. When the pickup bracket 2 is moved toward the outer surface of the disk 18 in the reverse order of operation, the rotary cam 14 is reversely rotated by the rack 10 to lift the holder shaft 8 and the hinge rod 9 ( The disk holders 6 and 6a are raised and lowered about 9a) so that the disk 18 can be taken out.

As described above, the present invention can install the rack and cam gear according to the movement of the pickup bracket to raise and lower the disk holder by the rotating projection of the rotating cam, and the fixing jaw and the disk holder on the deck before the disk is completely inserted. It is possible to prevent the disk from falling due to the stopper of the holder shaft of the system. It is possible to prevent the damage of the disk in advance, and there is no need to install a separate driving motor for the lowering of the disk. It is a useful design to see a lot of savings.
